The Lenovo Legion Slim 5 16AHP9 is a gaming laptop with a chassis that measures 359 mm wide, 260 mm deep, and 19 mm thick, giving it a relatively lean footprint for its category, with a total volume of 1,773.46 cm³. It weighs 2,300 g and relies on an active cooling system rather than a fanless design. The keyboard includes backlighting, and the laptop comes with a two-year warranty. It is not weather-sealed or splashproof.
The laptop features a 16″ LED-backlit IPS LCD panel with a resolution of 2560 x 1600 pixels and a pixel density of 188 ppi. It runs at a 240Hz refresh rate, making it well-suited for fast-paced content, and reaches a typical brightness of 500 nits. An anti-reflection coating is included, though the display does not support touch input. The system can drive up to 4 displays simultaneously.
The system is powered by an 8-core, 16-thread CPU clocked at 8 x 3.8 GHz with a turbo frequency of 5.1 GHz, built on a 4 nm process and supporting multithreading and 64-bit operation. It is paired with 32GB of DDR5 RAM running at 5,600 MHz across 2 memory slots, expandable up to 64GB. Storage is handled by a 1,024GB NVMe SSD connected via PCIe 4.0. On the graphics side, the GPU carries 8GB of GDDR6X VRAM, operates at a base clock of 1,230 MHz with a turbo of 2,175 MHz, and delivers 20.04 TFLOPS of floating-point performance alongside a texture rate of 313.2 GTexels/s and a pixel rate of 104.4 GPixel/s. It supports DirectX 12 Ultimate but does not include XeSS.
In benchmark testing, the laptop scores 11,009 in Geekbench 6 multi-core and 2,331 in the single-core test, reflecting the CPU's multi-threaded throughput alongside its per-core responsiveness. The overall PassMark result stands at 28,497, with a single-core PassMark score of 3,738. GPU performance is measured by a PassMark G3D score of 19,574, capturing the graphics subsystem's rendering capability under standardized conditions.
The laptop offers a well-rounded port selection, including two USB 3.2 Gen 2 Type-C and two USB 3.2 Gen 2 Type-A ports, with no USB 4, Thunderbolt 3, or Thunderbolt 4 ports present. Video output is handled by a single HDMI 2.1 port; there are no DisplayPort or mini DisplayPort outputs, and no VGA connector. Wired networking is covered by one RJ45 port, while wireless connectivity spans Wi-Fi 6E (802.11ax) down through Wi-Fi 4 (802.11n), complemented by Bluetooth 5.3. The laptop also includes an external memory slot and supports AirPlay.
The laptop is equipped with an 80 Wh battery and supports sleep-and-charge functionality, allowing connected devices to be charged even when the laptop is powered off or in sleep mode. It does not use a MagSafe power adapter.
On the audio side, the laptop includes stereo speakers, a 3.5 mm headset jack, and two microphones, though it lacks Dolby Atmos and an S/PDIF output. A front camera is present, while biometric options such as a fingerprint scanner and 3D facial recognition are absent, and there is no support for voice commands. Graphics features include ray tracing and DLSS support. The laptop does not include a stylus, optical disc drive, GPS, gyroscope, accelerometer, or compass.
The dedicated GPU is based on the Ada Lovelace architecture and comprises 4,608 shading units, 144 texture mapping units, 48 ROPs, and 12 execution units, with a memory bus width of 128 bits, a GPU memory speed of 2,000 MHz, an effective memory speed of 16,000 MHz, and a maximum memory bandwidth of 256 GB/s. It supports OpenCL 3, OpenGL 4.6, stereoscopic 3D, multi-display output, and double precision floating point, but does not include LHR. The system also features integrated graphics (Radeon 780M) and a CPU with a 115W TDP, a clock multiplier of 38, a maximum operating temperature of 100 °C, and a cache hierarchy of 512 KB L1, 8 MB L2 (1 MB/core), and 16 MB L3 (2 MB/core). The CPU supports instruction sets including MMX, AVX, AVX2, AES, FMA3, F16C, SSE 4.1, and SSE 4.2, has an NX bit, and operates across 2 memory channels with a maximum RAM speed of 7,500 MHz, though it does not use big.LITTLE technology and the multiplier is locked. Benchmark results include a PassMark DirectCompute score of 8,162 and an overclocked PassMark of 29,732, and the GPU contains 22,900 million transistors.
